Re: Preamps for 7D

"It also means that if you loop your master audio out of the H4n to the camera (you should use a padded cable to do this to convert line level to mic level) you will have a usable back up audio track on the camera in the event of a problem."

Thanks, Phil. But - if I plug my h4n into the camera to record audio, won't the AGC hiss still persist since there's no way to turn off the camera's preamps?
